This application is quite handy and small. It is coded in simple C. Every time it runs it reads the given header file and increments the build number.

Please note that this program is very basic, and apart from file checking it does not do any other checking.

Usage of the program is 
<source lang="dos">
buildrev.exe <filename.h>
</source>

The format for the header file is as follows:
<source lang="c">
#define BUILD 1
</source>

The #define and the BUILD is not important and can be changed to 
<source lang="c">
int build= 1
</source>

'''The code looks for the third field (separated by space) and increases that value.'''

The code is pretty straightforward and does not need much explanation.
